Metal identification

This requirement was addressed above but note that the marking has to be permanent and therefore has to be durable under the anticipated conditions of use. It would be wise to seek guidance from the customer if you are in any doubt as to where to place the marking or how to apply it. Metal identification plates stamped with the customer s identity, date of supply, contract, and limitations of use are durable and permanent. 

Tamper-proof seals are added to discourage unauthorized or undetected field adjustments. Once testing is complete, a metal identification tag (of soft lead, which is easy to imprint, yet impervious to corrosion) is attached to the SRV. The tag records the location number, set pressure, and test date. 

An intriguing problem about which we know very little is the mechanism of metal identification by the body that triggers Its response, as in the case of the huild-up of metallothioneins upon exposure to toxic metals. Perhaps the best understood of the metalloregulatory proteins is MerR that protects bacteria from mercurial toxicity. It is extremely sensitive to Hg, and distinguishes it from its congeners Zn and Cd. There is good evidence that the mercury receptor forms three-coordinate mercury(II) complexes (see Fig. 12.1c), making possible this specificity. ...

Chemical analyses can be used, but for most metals one needs only to know the major elements such as copper and tin. Chemical identification of metals does not require either high precision or trace sensitivity. X-ray fluorescence has often been used in metal identification and has recently been developed into portable, nondestructive devices for field and museum use. X-ray diffraction can identify metals structurally, but this can be complicated by more than one compound in complex alloys such as steel.
